Abstract

The monotypic Brazilian genus <i>Sickius</i> Soares &amp; Camargo 1948 is revalidated, rediagnosed, and tentatively transferred to the <i>Ischnocolinae</i>. The formerly unknown female of S. longibulbi Soares &amp; Camargo 1948 is found to lack spermathecae. This unusual genital feature, not found in any other mygalomorph spider species, is described and discussed.
